what is the diff between molarity and molality value of a solution??? which is temperature dependent?

Expert Answer:

"Molarity" refers the numbers of moles of the solute present per litre of the solution.

"Molality" refers the numbers of moles of solute present in 1000 grams of the solvent.

The molality of a solution is calculated by taking the moles of solute and dividing by the kilograms of solvent.

Molarity is temperature dependent as it involves volume, and volume is affected by temperature. We know as temperature increases, solutions tend to increase slightly in volume.
